China Heavy Duty Free Forging Hydraulic Press Machine

Hydraulic open die forging press is specialized in various upsetting, piercing, stretching, flattening process. Various parameters like pressure, position and time can be set and instantly displayed on line. The press is mainly used in thermal power generation equipment industry (such as steam turbine vanes), wind power generation equipment industry (such as flanges), pressure vessel industry, petrochemical equipment industry, metallurgical equipment, aerospace industry, railway industry. Main features of the press include lower noise, Energy saving and environment friendly, full automation and easy maintenance.
